ADDRESS. 
upwards of 2000 of which, amongst the Ilymcnoptcra and Diptcra, 
arc not British. 
Since the publication of the last number of this work in Januarj^ 
1837, I have been unwearied in my endeavours to obtain a com- 
plete census of our indigenous species, and have proceeded to a 
considerable extent in working up an amended edition of my 
Catalogue (or Nomenclature), by patiently re-examining the re- 
ferences to every species and synonym, attaching the actual date 
when possible to every reference, and re-arranging my collection 
on a novel pi ai, to correspond exactly with every name, both 
specific and synonymical : a proceeding which the possession of 
the largest collection of British Insects, and probably the most 
extensive Entomological Library (about 1500 volumes), have ena- 
bled me to perform with some prospect of success, especially now 
that my time is solely at my own disposal. This Nomenclature it 
was my full intention to print with the continuation of the Illus- 
trations ; whether, however, it may now ever see the light is pro- 
blematical : it will not be my fliult should it not, for no person has 
more sincere cause to regret the abrupt termination of this work 
than myself, having not only devoted the greater portion of a not 
very short life towards its prosecution, at a cost of nearly £10,000, 
in the formation of my Collection and Library, and in the expense 
of publication ; but as a consequence of loss of time in defending 
my copyright in 1832-3, my prospects were for ever blighted, by 
the inconsiderate prejudices of an implacable and tyrannical in- 
dividual : thus compelling me, in the decline of life, to embrace 
the first opportunity that presented itself, of relieving myself of 
the thraldom of office, and of retiring in comparative penury 
therefrom I 
Contrasted therewith, I have now in conclusion the pleasure 
sincerely to return my thanks to my Subscribers generally, for 
their support, and more particularly to the following gentlemen, 
— amongst whose names will be found those of the persons most 
eminently distinguished for their respective attainments in the 
various branches of natural science, in this country, — for their 
recent exertions on my behalf.
